Blade-J Kara Women's Dress, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Bijouxia Hoop Earrings Openwork 18 Carat Gold Plated,Dickies IN30030 NRB50 Size 50 "Industrie" Trousers - Navy Blue/Royal Blue}These studs promote higher friction torque^{BJYG Child Safety Net Protection Climbing Frames Nylon mesh multi-function}and improves performance, especially in runs with change of direction,^{Royce Leather Men's Magnetic Money Clip in with Suede Lining Belt,adidas Unisex Kid's Cf Racer Tr K Competition Running Shoes}compared with round-J Kara Women's Dress. On the other hand, runs with fast changes of direction associated with high boot traction can increase the mechanical overload, especially to the knee joint, causing a potential increase in the risk of anterior cruciate ligament (ACL) injuries.^{John Deere State Pride Farm Ss Tee,Dragon Alliance Fame Sunglasses-ICE CARATS 925 Sterling Silver Plate Square Band Ring Size 5.00 Stackable Fine Jewellery For Women Gifts Her}Besides that, the greater traction promoted by the penetration of the studs in the lawn can promote greater peaks of pressure on the sole of the feet,^{Child Safety Net Protection Climbing Frames Color multi-function protective net safety nylon rope net}as well as greater incidence of metatarsal stress injuries.^{Nike Womens Zoom Winflo 5 Running Shoes}

Subsequently, the duplicates were removed and the abstracts were read to identify those who met the inclusion criteria: articles written in English, original studies,Clarks Women's Hamble Oak Derbys, studies related to the influence of boot studs. After exclusion of articles that did not meet the inclusion criteria, the remaining articles were selected to be fully read and those that did not investigate overload due to the use of blade-Clarks Women's Hamble Oak Derbys. The following information was selected in each article included: author, year of publication, methods, footwear model used, evaluation instruments, dependent variables and results. To minimize the chances of not finding all the articles that fit the scope of this study, the references of selected articles were also checked.
